Split 

Tip or Ring of one pair is split with the Tip or Ring of another pair 

 

Locating ground faults are more difficult due to multiple ground signal return paths.  It is 
recommended to locate shorts or crosses whenever possible.  Otherwise it may be helpful to 
remove shield ground at the transmitter location, then connect the transmitter leads to the 
faulted wire and shield. 

 

The cable length beyond the fault should be as short as possible.

Pair Split 

During identification of the split, the technician must identify the two pairs involved in the split and if the 
tips or rings are split. The diagram below shows a split and how to place temporary short at the end of the 
section.
